The warm waters discharged from industrial facilities, in particular electrical power plants, can foster the development of amoeba. The discharge and environments affected are all subject to special monitoring.
Bathing can entail health risks when the local environment is assumed to contain high amoeba concentrations and when the bather inhales water droplets. The risk results from the concentration of amoeba pathogens in the water. This is particularly true of children, who are a favourite target for amoeba.
